As indicated by its latin name parvovirus is a very small viruses responsible for the well known and so feared disease called Parvovirus.
The Parvovirus affects canineyoung s from 6 weeks to lose the maternal immunity , is uncommon in adult animals because they are already immunized by vaccination or subclinical infections.
The estimated incubation period is 5 days.
The source of contamination is the stool of animals who have contracted the infection. There may be a large amount of virus in their fecal faeces of animals who suffer from the disease. The virus is resistant under extreme climatic conditions and can survive for long periods, but is sensitive to (chlorine bleach) sodium hypochlorite disinfection as environmental treatment in caniles, dog kennels and infected territories funds is recommended.
The parvovirus is not contagiousso man or other domestic animal species. Presentation more often is the digestive producing a viral hemorrhagic gastroenteritis, the virus infects the cells bowel (enterocytes) and replicates causing necrosis and cell death mechanism responsible for the symptoms.
The symptoms frequently you are listed in chronological order of presentation:
** Decay and depression (early days)
* Anorexia (loss of appetite)
* Fever (between 40 and 41 (c))
* Vomiting(sparkling as whipped egg clara) s
* Bloody diarrhea
* Dehydration (due to vomiting and diarrhea)
The puppies more small are the most suffering from shock and death that can occur in a matter of days after the diseasewas declared. This disease has a high morbidity and mortality, with tratamiemto the indices of mortality is reduced significantly.
The veterinarian may give his initial diagnosis based on the signs clinical, but only after taking into account other causes that could cause the vomiting and diarrhea (diagnostic differential) is often necessary to confirm the diagnosis by laboratory tests.
The disease is quick incubation and acute, or that the virus kills the animal in the first ten days, if does it not, the puppy form immune defenses and destroy the virus. If the puppy from the time that performs the first bowel movement with blood, survives 7 days it is very likely that it survives, being very critical 4 days which is when, generally, the fatal outcome occurs, if on the fourth day the puppy stops vomiting, walking, begins to move the queue, there is hope to be saved, but it is a very serious disease that you never know certainly that it will happen in those ten days.
Another way to much less frequent parvovirus is the inflammation of the heart (myocarditis). This presentation occurs without gastrointestinal symptoms and viral infection occurs in the cells muscle of the heart (myocardium), affects very young animals (weeks), and is a cause of sudden death, puppies who survive may be with a permanent heart defect.
